How to tell the Red Arowana from the bad?
1. Dragon whiskers: a pair of tentacles are very important to arowana. Good arowana tentacles are vertical, and the color with the fish body, twists and turns, broken beard, two irregular tentacles will affect the appreciation.
2. Eyeballs: the big and bright eyes are the energy address of the arowana. The arowana's eyeballs are huge and excellent like searchlights.
3. Head: the epidermis on the top of the head should be smooth and bright as far as possible, without wrinkles.
4. Mouth: the upper and lower lips should be tightly closed. If the lower jaw is excellent or has a tumor-like protuberance, it cannot be said to be a good mouth shape.
5. Scales: the scales of arowana are large and regular, and they look glossy. If they are mottled, they are worse.
7. Pectoral fins: expand as much as possible, neatly and in direct proportion to the body.
8. The back three fins: the fins need to be expanded vertically. Zigzag and zigzag are not interesting, the caudal fin should be large, and it will not show the appearance of shrinking fin when reversed.
How do you know if the dragon Fish is healthy?
A way to judge whether arowana is healthy or not
1. Observe the water quality
Water quality is one of the key points to judge the health of arowana. If the water smells fishy or there are bugs in the water, then the health of arowana is worth worrying about. Because these situations show that the content of organic matter in the fish tank is too high, that is, the virus and bacteria in the water will also increase sharply, then the dragon fish will also be in danger.
Therefore, in order to raise arowana well, it is very important to change water regularly and quantitatively and to maintain good water quality. Usually, we should pay attention to the timely removal of floating foreign bodies in the fish tank, precipitated foreign bodies at the bottom of the tank, residual Feed, feces and other substances. Otherwise, the water is easily seriously polluted by these foreign bodies, and at that time, a large number of water will have to be changed, and at the same time, according to the actual degree of pollution, it is necessary to decide whether to scrub the fish tank and use drugs to disinfect it, so as to ensure that the water quality is clean and hygienic.
2. Observe the state and food intake of arowana.
In raising arowana, we must learn to observe arowana from its shape, shape, body color, flippers and other aspects. Generally speaking, the sails of healthy arowana will be very wide, and the fins are intact, there will not be fins beating willow or fin decay phenomenon, and the arowana's body surface color, there will be no obvious trauma.
On the other hand, the body color of sick arowana tends to fade or blacken until it turns black completely. When it is observed that the arowana is listless, or always huddled in the corner without eating or playing, attention is paid to it.
In addition, if the swimming posture of the arowana is abnormal, such as back swimming, head sinking and so on, it can be concluded that the arowana is abnormal and timely measures should be taken to deal with it. In addition, usually in the process of feeding the arowana, if it is found that it is not interested in the bait, or eat very little, it also shows that the arowana is abnormal, it should be carefully examined and properly dealt with.
3. Observe the body surface of arowana
Usually, the mental state of arowana has a lot to do with the change of the environment. Arowana is timid and sensitive, once its surrounding environment is a little abnormal, such as the sudden emergence of acousto-optic signals, it will cause it to be frightened, and lead to a series of problems.
The second is to observe whether there are white spots, water mold, standing scales and other common diseases on the body surface of the arowana; pay attention to whether there is obvious trauma on the arowana body, the above phenomena can be well observed by the naked eye. If you find the above abnormalities in the arowana, you must deal with them in time and treat them as soon as possible to minimize the damage to the arowana.
4. Observe the eyes and mental state of arowana.
If the arowana swims freely, it means its mental state is good; if the arowana swims slowly, or always hides in the corner, it means its mental state is bad. In addition, if it is observed that the operculum of the arowana is dilated and closed weakly or too hard, or surfacing to the surface to breathe, it shows that it is difficult to breathe. This situation is mostly caused by lack of oxygen in the water or arowana disease.
Careful observation of the arowana's eyes can well judge its physical condition, the arowana in good condition is often clear-eyed, and the eye rotation is flexible, while the poor arowana will become dull. If it is observed that the arowana's eyes are dull, it is to strengthen the observation and management of the arowana.
5. Observe the faeces of arowana
Generally speaking, arowana will defecate after eating for half an hour. how many times a day can arowana defecate, which needs to be determined according to the number of feeding times. In addition, the normal feces of arowana are oval and granular, with black, brown, brown and other colors. If it is found that the arowana's feces are white, or if its feces has a thread connected to its asshole, then the arowana may be suffering from mild enteritis.
In addition, other diseases can be judged by observing the color of arowana feces. For the arowana that daily feed on small fish, shrimp, Loach and other food, their feces are generally brown, black or with a little red. If the arowana has white stool, defecate, hollow stool or purulent stool, it generally means that it suffers from enteritis or intestinal disease and needs timely treatment.
Dr. claw warm tip: raising arowana, daily observation of its state is very necessary, timely detection of arowana abnormality, can reduce arowana disease and harm.
How to distinguish between arowana and arowana in more detail
Golden arowana, no more than 40,000 are garbage, a good golden dragon, the body will glow with golden scales, looks like wearing a piece of golden armor. The landlord might as well have a good eye when buying and see clearly. To buy a golden dragon, you must first look at the eyes of the golden arowana. Normal arowana eyes look flat or upward. If the eyeball looks down and cannot rotate upward, that is.How does the dragon fish look good or bad?When we talk about [eye-catching], this is not a disease, but fish farmers who put small fish fry when they are young.How does the dragon fish look good or bad?He chased the food for a long time, and the muscles above his eyes became thicker, so he couldn't go up. This is the first point. Second, we must see clearly whether there are any scales on the body, or if there are black spots in any part of the body, which is caused by the fish in the past because of illness. There are scales can not fall off, after the loss of a piece to grow back is not beautiful, not perfect. With scars. Keep in mind the landlord. Third, check the two beards on its mouth to see if it is broken or not straight. If it is broken and grows back, it will be curved and not good-looking. The last thing is to see if his tail is rotten and forked. Red tendons and so on. Because of a good golden dragon, he is of high value. The golden dragon of small fish fry is usually about 10, 000 yuan, and the big 35CM starts at 3, 000, 000. The bigger one is more expensive, 150000 yuan each.How does the dragon fish look good or bad?I've seen it all. Horror. It is recommended that the landlord, buy arowana, not too hasty, because it is not to buy vegetables, this is a matter of tens of thousands of yuan, so to see clearly, look at a few more to compare. When you buy it, remember to see if there is a [chip] on the arowana, which represents that he was born at that time, how old he was, and so on. I might as well say that if you can raise arowana, any arowana you raise is beautiful, and you personally feel that it is not worth spending so much money to invest in a fish. It is already very good to raise 1000 murmurle 2 to 3000 red arowana, because fish farming, after all, is risky, and when you are sick, we can only speculate what to use to treat it. Some things are easy to say, but it is not good to raise them. In case of KO, I will have a headache. Landlords can check on the Internet, many people raise KO fish, do not say in the heart, early know not to buy. If the landlord really has a lot of money, it doesn't matter.
How to distinguish between arowana and arowana
1 Dragon beardHow does the dragon fish look good or bad?A pair of tentacles is very important to arowana. Okay, arowana tentacles are straight.How does the dragon fish look good or bad?And the color is consistent with the fish body, curling, broken beard, two irregular tentacles will affect the ornamental effect.
But sometimes the beard of the arowana will be unfortunately broken, at this time, we can put a certain dose of antibiotics in the water to prevent infection, and then pay attention to nutrition, the broken beard will grow out automatically, but whether it grows straight depends on your skills and the arowana itself.How does the dragon fish look good or bad?Yes.
2 eyeballs: large and bright eyes are the spirit of the arowana. The arowana's eyeballs are huge and protruding like searchlights and rotate flexibly. It's beautiful. Whether you can get good results or not depends on your management of water quality and the way you feed.How does the dragon fish look good or bad?Yes. The arowana that preys on the food at the bottom of the aquarium box for a long time will get ptosis.
3 head: the epidermis on the top of the head should be as smooth and bright as possible, without wrinkles.
Mouth: the upper and lower lips should be closed tightly. If the lower jaw protrudes or has a tumor-like protuberance, it cannot be said to be a good mouth shape. In addition, pay attention to whether the color of the upper and lower lips is the same as that of the fish.
5 scales: the arowana scale is large and neat, looks very glossy, if there are spots, it is worse. If the arowana scales fall off, they will grow out by themselves. Don't worry about it.
6 gills: neat, shiny and not sunken is a requirement for the gills of arowana. In addition, the cheek rake should not curl and turn out.
7 pectoral fins: stretch as far as possible, neatly and in direct proportion to the body.
Back three fins: (anal fin, dorsal fin, caudal fin) fins require straight extension. Bending and bending are not ideal. The caudal fin is bigger. And the phenomenon of shrinking fins will not occur when turning. If you pay attention to these, you can choose and compare excellent arowana. In addition, some congenital or acquired malnourished fish will have spinal curvature deformities, so we should not buy and raise such fish.
When you see the golden arowana, how to simply look at the grade of the fish and distinguish between the good and the bad?
How to distinguish between golden arowanaHow does the dragon fish look good or bad?The quality of arowana is a vague concept for those who raise arowana for the first time.How does the dragon fish look good or bad?Fish friends often post to ask whether their golden arowana is high-backed or over B and so on. Here is a brief explanation with the method of illustration.
At present, the Jinlong arowana on the market is divided intoHow does the dragon fish look good or bad?The gem has a high back and B has passed the back.
(on the basis of over-back, if the gold nugget of the golden dragon fish's head is greater than 70%, it is called gold-head over-back.How does the dragon fish look good or bad?Here, the unification has been memorized to introduce).
The premise to distinguish the quality of Jinlong arowana is that the body length of arowana should be more than 20 centimeters.
When buying arowana, it is best to choose the arowana with a body length of 20-25 cm, because the performance of the arowana is already very stable at this time.How does the dragon fish look good or bad?Can see the quality of the pros and cons is also easy to raise, the length of less than 20cm arowana is difficult to distinguish the quality of most friends, so we should pay more attention to the selection and purchase.
Gem golden arowana standard: scales bright to the fourth row of bead scales do not show
High-backed golden arowana standard: the scales are so bright that the fifth row of bead scales do not show
B over the golden arowana standard: the fifth row of scales is not all bright
Over-back arowana standard: the sixth row of scales, bright beads, all bright scales
The number of rows of scales-the key depends on the lateral hole. The lateral line hole is a row of holes in the lateral scales, this row of holes is the third row of scales, and the upward number is the fourth row, the fifth row and the sixth row.
Pearl scale-the so-called pearl scale, refers to the small garden scale near the root of the back three fins of the arowana, named for its shape. Correctly, the small garden scales near each of the posterior three fins are pearl scales, which can also be called scale fragments.
Pearl scale is the key to quickly distinguish the quality of golden arowana.
Pearl scale is the largest marker to determine the arowana gene, climbing scales early and late, mainly depends on the performance of pearl scales.
The jewel and the high back can not see the pearl phosphorus at all:
B half brighter than pearl:
All the phosphorus on the back is bright:
The performance of the pearl scale represents the bloodline of the golden arowana, and the brighter the pearl scale is, the more positive the pedigree is.

How to choose arowana?
First of all, a sub-adult arowana of more than 30 centimeters, it has almost more than 70% of the conditions have shown due characteristics.
In appearance, as long as there is a basic understanding of arowana, with relevant arowana information, the probability of buying the wrong arowana is less.
The key point is the shopping skills below 20 cm and the judgment of fish. Because the same species of arowana, the bigger the more expensive is absolute, relative to the little dragon, there is a price gap, but the same fetal fish will also be good or bad, so we must pay special attention to observe some slight differences.
The first and fourth principles should be borne in mind:
1. Look more: whether you go to Longyou's home or to the aquarium, you need to observe the characteristics and growth changes of arowana of different shapes and qualities.
2. Read more: read related arowana books, magazines and browse the arowana website information to enrich the arowana knowledge and cognition.
3. Ask more questions: read and read more to understand the basic knowledge of arowana. When you have doubts or different opinions, you should have the spirit to ask experienced people.
4, more comparison: comparison of goods is the only rule to choose and buy arowana. It is a correct concept to compare shape and quality with the same price and the same price. But the premise is that we must understand the shape, quality and price of arowana, otherwise random bargaining is a random description of the grade, which will be regarded by the store as an unwelcome guest.
II. Basic General principles for the selection of Little Dragons
To be straight, long and powerful, the darker the shadow on the side of the beard, the better, and if the beard can show kumquat red, the better.
The upper and lower jaw should be close, and the lower jaw should not be more protruding than the upper jaw, so as to avoid the bucket shape when you grow up, and it is better for the lips to show redness.
To be bright and bright, not too big, the white part of the eye is basically golden or part of orange, the more red part, the better, while the outer edge of the eyeball needs to show a dark green metallic luster, the more three-dimensional, the better.
To be smooth and smooth, with silver metallic luster, faint turquoise is better, the soft wing of the outer edge of the Gill is smooth with the breath, not everted.
5. Pectoral fin:
To be broad and long, the first main fin bone should have a smooth arc, the spine and fin membrane are complete, the red is naturally rendered inward from the fin edge, and the tip of the outer fin is yellow, bright gold and pink.
6. Ventral fin:
The fin bone and spine should be smooth, and the redness should be rendered by the base of the extroverted fin. The redder the better, the outer edge can have yellow and bright gold powder color.
To be complete and orderly, there should be no missing corners on the scale edge. At 12: 15 cm, the bright scales will reach the fourth row, and the high-quality dragons will show up to the fifth row.
On the other hand, those who show pink glossy edge color and special purple or blue sky luster when swimming, have a strong sense of metal, and must be able to present a scale frame outline at 15: 20 cm and the clearer the better.
8. Dorsal fin, anal fin:
The stripes and fins should be complete, and the redder the color, the better. The markings of the black tigers submitted with the fins are obvious, and the stripes of the dorsal fin and anal fin tigers are relatively good.
9. Caudal fin:
To be broad, the fin is divided into two and then divided into four, if it can be divided into six * better, to fully expand, do not shrink the tail.
The shadow frame of the caudal fin at 12: 15 cm, called the tiger pattern, has two and three frames, the more obvious the better when small, but the wheel frame will gradually disappear as it grows, and the redder the better.
10. Swimming posture:
When swimming, the pectoral fins spread out, like flying, not in a hurry, not afraid of people's wait-and-see, examination, the arrogant is better.
Third, how to observe the scale level and background color of Xiaolong
Usually when we visit the aquarium or buy arowana, the upper lamp or water lamp is always lit on the aquarium, and the lamp is usually a plant lamp with a reddish spectrum.
In addition to lighting, the most important thing is to enhance the color performance of arowana and make it more red and beautiful when appreciating, which is normal.
When shopping, its swimming posture and other parts can be observed under the lighting, which makes it clear at a glance, but when observing the scale level and the scale background color, due to the direct light source irradiation, the bright scale will reflect too strongly and blur the scale layer. the background color of the scale will also be distorted by the red light.
Therefore, when choosing and purchasing, if the situation permits, you can ask the store to turn off the lighting of this cylinder and observe it only by the light source in the store.
At this time, you can feel the luster of the bright scales on the small dragon fish, and you can clearly see the layers of the bright scales and the faint color of the scales when swimming.
If you can't really see it in this way, you can further trouble the shopkeeper to take an upper lamp, which is in the middle and lower position of the fish tank and rotates up and down from the outside to the inside. Through the irradiation from different angles, the reflection of the scales can be seen more clearly.
Fourth, pay attention to the problem of improper promotion in the selection and purchase of Xiao Honglong
Because the red dragon is a precious ornamental fish, and the basic requirement of the red dragon is to be red, a small dragon below 20 centimeters needs to have good pedigree genes in order to show the obvious characteristics, redness and scale levels of the red dragon.
However, often due to consumers' lack of business ethics exporters or fish farms, they take advantage of the weakness of consumer ignorance to use improper techniques to make the hair color of ordinary dragons more attractive, and sell them to consumers at the price of ordinary red dragons with the shape of deceptive top red dragons, so that consumers still think that they have taken advantage and bought top red dragons.
Generally speaking, it is inappropriate to promote the color:
1. Holmonga synthesizes red pigment:
Generally speaking, the small dragon fish that use this strong technique mostly use inferior red dragons or hybrid dragons, such as the first half dragon or the second dragon, while the small dragons less than 15 centimeters have little difference in shape, but their fins are blood red, which makes inexperienced consumers suffer losses.
2. Feeding synthetic red pigment:
This technique is usually used in the No. 1 red dragon, which makes the fins of the dragons less than 20 cm bright red, and some dragons even eat pink all over the body. Sometimes this method is also used in 30 cm 40 cm adult dragons, making the fins and scale frames more bright red. When consumers do not notice the purchase, the color will gradually fade 3-4 months after purchase.
3. Hunger promotion method:
Normally raising arowana can grow to about 30cm to 36cm a year, but some exporters or fish farms will starve the ordinary arowana to slow its growth. An one-year-old red dragon only grows to about 20cm, while a normal 20cm dragon only takes 5 to 6 months to grow.
This kind of over-age red dragon, due to the age of the fish, the scale frame will be obvious, and with a little artificial pigment, its shape and quality is as attractive as the top red dragon. However, this kind of red dragon can be seen with a little experience, for example, the larger eyes are out of proportion to the body, and it is easier to shrink the fins when the back three fins swim.
4. Blind dragon technique:
According to experience, blind dragons born with visual impairment or lack of eyeballs have dark body color but strong red because they live in the dark world, so some immoral fish traders use lasers or other cruel means to destroy eyeballs when they are young dragons. Make the dragon amblyopic or completely blind, stimulate the body color and then sell under different names.
Hope the building master to adopt, support my motivation.
